I've noticed that the mobs are respawning extremely fast in MoP, to the point where the moment they die the respawn aggros me and comes swinging. I was trying to rescue a farmer from the Mogu and whenever there was a mogu near the farmer would go into fight mode and not be able to be rescued (click on and conversed with) and even though I was killing the mogu quickly I couldn't get the farmer because the Mogu kept respawning.Then there were places where the mobs spawned so quickly that I created a cloud of baddies who, even though I was a demo warlock and really good at aoe killing in dragon soul or better gear, I could not kill faster than they respawned. I had to carry the cloud to a different location to finish the fighting. I did however pull down lots of cloth for my tailor. I get that there needs to be enough spawns for people to level properly but they need to turn it down from 11 to 10.
